As but a slight frictional contact exists between the smooth under face 12 of the d isk and the record 13 upon which it Tests, the needle 23 will readily hold back said disk against rotation and Without experiencingappreciable stress. This condition will obtain until the said needle reaches the end of slot 25 and which corresponds to the end of the selection of the record. As the disk 11 is then no longer restrained by said needle, it will rotate practically instantaneously (in the. direction indicated by the arrow) under the action of the rotating record 13. and will then causo the said needle to ride upon the inclined portion of the surface 21 adjoining the spiral portion of the, barrier 2K1, or possibly upon the inclined portion 2S, choosing the In Fig. 1 path ot the disk 11 is indicated of the drawings the general needle relatively to the by dashes. In any event the needle will, under the guidance of the bai-rie 22 or 24, be returned toits initial and start ing position in slot 25 and the cycle repeated. The function of the weighted. arm members-14 and 15 is to power to effect the return ot said needle, 'for the slight frictional contact between disk and record would be quite insuliicient tor this purpose. It is pa fticularly desirable that this should be so as the needle would otherwise be placed under undue stress during the period of reproducing and an attachment of the repeater to the tone. arm 'or other portion of the talking machine bccoine necessary. By properly proportioning the radii of gyration of these masses and the masses themselves, a suitable angular moment-um is obtainable and is designed to eifect proper action at the lowest speeds usually employed with the record.
